MACHINE FOR SANDING BUTTER-TUBSC.

SPECIFICATION forming part of Letters Patent No.

Application filed August 5, 1896.

To all whom, it may concern: Be it known that I, CHARLES D. AMEs, a citizen of the United States, residing at Portland, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Machines for Sanding Butter-Tubs and other Casks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention has reference to machines for smoothing the exterior of butter-tubs, pails, barrels, and other casks; and it consists in certain novel mechanism for presenting the sand-belt to the exterior of the tub, mechanism for rotating the tub meanwhile in the opposite direction from the movement of the sand-belt, sand-belts of peculiar construction, and mechanism for varying the position of said sand-belts on the carrying-pulleys to adapt such belts to tubs of various sizes.

I attain the above results by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective of that portion of the machine embodying my invention. Fig. 2 is a detail in cross-section of the pulleys which carry the sand-belt.

Similar numerals refer to similar parts in each view.

The frame 1 of the machine is suitably supported a proper distance from the floor by means of the legs 13. Parallel belt-pulleys 2 2 are suitably journaled in line and the proper distance apart on the frame 1 and adapted to carry and in their rotation to advance the sand-belts 12 and 14. A tension device 3, consisting of a threaded shaft adapted to be rotated by the hand-wheel 16 and seated in a threaded box 17 suitably attached at its inner end to the boxes of one of the pulleys 2, serves tokeep the belts 12 and 14 at the proper degree of tightness. This is further accomplishedby the idle-pulley 6, seated on the frame of the machine under the upper half of the belts 12 and 14 and adapted to hold said belts up against the lower surface of the tub being operated upon thereby.

573,846, dated December 29, 1896. Serial no. 601,734. (No model.)

The tub-chucks 1O 10 are respectively suitably journaled transversely in each end of the beam 8, which beam is pivoted about centrally to the vertical standard 18, formed on frame 1. The chucks 10 10 are adapted in the usual mode for thereception of the but .ter-tubs in position to project over the upper surface of the upper portion of the sand-belts 12 and 14. The sprocketwheels 9 9 are seated on the axles of the chucks l0 10, respectively, and are adapted to be driven in a direction opposite to the movement of the adjacent side of said sand-belts by the sprocket-chain 7, which passes around both of the sprocket wheels 9 and a lower sprocket-wheel 19, seated rigidly on the face of the gear 4:, suitably journaled on the lower portion of the frame 1. Rotation is imparted to the gear 4 by the engagement therewith of a pinion '20, seated 011 the face of the belt-wheel 21, the latter being driven by the crossed belt 22 from the small pulley 23 on the shaft of one of the sand-belt pulleys 2.

The draw of the sprocket-chain 7 tends to normally hold down upon the belts 12 and 14 the chuck 10 at the left in Fig. 1, and while the chuck at the opposite end of the beamyS is in operation the chuck 10 thereon is held down by the operator by means of a foottreadle, hand-lever, handle, or other suitable device. While the tub upon one of the chucks 10 is in contact with the sand-belts 12 and 14, the opposite chuck 10 is elevated above and out of contact with said belts, and the finished tub thereon removed and another 1111- finished one placed upon said chuck, which is then depressed into contact with said belt either by direct pressure by the operator or by the draw of said chain 7, as the case may be, and the tub upon the opposite chuck removed and a new unfinished one placed thereon. In this mode each end of the beam 8 is depressed and elevated alternately with the opposite end, and during thedepressed intervals the exterior of the tub carried upon the depressed chuck is brought in contact 'with the sand-belts 12 and 14 and such exterior finished by said contact, while in the elevated intervals of the chucks 10 the finished tub is removed therefrom and an unfinished one substituted therefor.

Suitable rotation is imparted to either one ICO of the belt-pulleys 2 by any of the well-known modes. I employ a small belt-pulley rigidly seated on the shaft of one of the pulleys 2 and driven from the line-shaft in the factory by means of a short belt.

On the exterior of the butter-tub, when placed on the chuck 10 for the finishing of its exterior, as aforesaid, there are two narrow rings or truss-hoops, one at the bottom of the tub and the other a short distance downward from the top of the tub. The presence of this upper ring necessitates the use of two belts. The broad belt 12 occupies and operates upon the interval between said hoops, while the narrow belt 14 operates upon that portion of the exterior of the tub 3 which extends above the upper ring or truss-hoop. By this means all of the exterior of the tub is finished except the narrow belts occupied by the aforesaid rings or truss-hoops; but when the tub is finished all of the exterior of the tub which is exposed to view has a finished appearance.

As tubs are constructed of different heights, the spaces between the aforesaid rings and the upper ring necessarily vary in width. Therefore some provision must be made for the use of sand-belts of proportionate widths and means provided fol-holding said belts in proper position relative to the area of the tub upon which the said pulleys are to operate. To that end I provide two two-and-on e-halfinch iron bands 21 and 25, placed around the periphery of the pulleys 2 parallel with each other and held in place by a suitable number of bolts 26, the heads of which are countersunk in the iron bands 24 and 25, and the stems of which pass through the rim of the pulley 2 in openings 27, which latter may be either transverse slots or a transverse series ofbolt-seats, and are rigidly held in place by nuts 28 on the inner end of said bolts. By this means the iron bands or bushings 24; and 25 may be shifted at will transversely on the periphery of the pulleys 2 to serve as seats and guides for the sand-belts 12 and 14, operating upon the belts like a crowning pulley.

The belts 12 and 1% are constructed of leather, havingapreparation of glue and sand on their outer surfaces to operate against the exterior of the cask, as aforesaid.

Any other material may be used for the belts, but leather is found to be preferable.

If preferred, the machine may be used with but one of the chucks 10.

lVhat I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. In combination with suitable mechanism for presenting the exterior of casks to the exterior of amoving sand-belt, the sand-belts 12 and 14;, suitably carried on rotating pulleys, andon their outer surfaces provided with a coating of glue and sand and duplicate means for presenting an article to the belts, substantially as shown and for the purpose described.

2. The combination of the sand-belts 12 and 14, suitably carried on the rotating pulleys, and provided on their exterior with a cuttingsurface of glue and sand, oscillating beam 8, provided with a tub-chuck at each end, adapted to be alternately'presented to said belt, and means substantially as shown for rotating said chucks meanwhile in an opposite direction to the movement of said sand-belts, for the purpose specified.
